As it happens, your obituary of Arthur C. Clarke appears in the same issue as your ruminations about the future of Heathrow (“How to Fix Heathrow,” March 29, 2008). The chaos at Terminal Five—which started after you went to press, and which is still out of control—completes the picture. Space travel? Colonization of space? Forget it. The human species is not capable of organizing even the earth travel, let alone the travel to our nearest neighbors in space. And we should never forget that the colonization of this planet was a sordid affair, too. To wit, Clarke’s wish and expectation that we will evolve until we become “like gods” will forever remain in the domain of science fiction. At best, we may hope that we will evolve until we can fix poor old Heathrow. The way things look at the moment, even that smacks of unadulterated science fiction.
